Erzya and Mordva of the Nizhny Novgorod Region — the Finno-Ugric peoples indigenous to the south and east of the Region: Erzya, Moksha, and the Teryukhane — a northern group of the Erzya from the Teryushevskaya volost of Nizhny Novgorod Uyezd. The fortress at the mouth of the Oka was founded in 1221 in a land of Mordva settlements, and this thread runs from there to the present-day Erzya villages of Lukoyanovskiy and Bolsheboldinsky Districts. Below is the full scope of the collection: the peoples and their history, pre-Christian beliefs and Christianization, villages and places, daily life and costume, language and place names, notable people, museums, and festivals.
